The Cache Calibration Controller is a hardware and software project for astronomers. It provides an interface for controlling relay devices from popular astronomy software such as N.I.N.A.
- Relay control via Alpaca 1.0 protocol
- WiFi connectivity with ESP8266 microcontroller
- User-friendly web interface for device setup and control
- Persistent relay names stored in EEPROM
- ESP8266 Microcontroller
- Relay module(s)
- Install the Arduino IDE.
- Open the
cachecalibration.inofile in the Arduino IDE. - Install the required libraries via the Arduino IDE's Library Manager:
- ESP8266WiFi
- ESP8266WebServer
- ESP8266HTTPUpdateServer
- EEPROM
- Upload the sketch to your ESP8266 device.
Once the software is uploaded to your device, you can access the web interface via a browser on any device connected to the same network. From there, you can control individual relays, change relay names, and set up WiFi credentials.
On first boot, the device will launch a WiFi Access Point named 'Cache_Calibration'. Connect to this network using no password. Once connected, open a web browser and navigate to 'http://192.168.4.1'. Here you will find a WiFi configuration interface. Select your WiFi network from the list of available networks, enter your network password, then click 'Save'. The device will disconnect from the Access Point and attempt to connect to your WiFi network using the details you provided. Once connected to your WiFi network, the device will be accessible at the IP address assigned to it by your router.
The WiFi Access Point named 'Cache_Calibration' is only open if the wifi configuration is invalid or not available. But if you want to change your wifi configuration you can go to 'http://<the_ip_of_cache_calibration>/reset' and wait 5 second. After that 'Cache_Calibration' is available like first boot.
